Residents across Chesapeake Bay experience considerably louder noise than other nearby communities because the artillery's blast sound is highly directional. Something had to be done.

The steel construction allows for it to be lifted into position and used when firing at a 30-degree elevation. But it cannot be attached to the turret, because tests showed it affected recoil and harm the turret barrel.

The Firearm Blog also found a patent for a potential tank silencer, which would attach to the muzzle of the tank's main turret.

Seems cumbersome.

The holes on the silencer are kept as small as possible to keep the decibel levels lower, which is most effective behind and in front of the suppressor. The total cost of the construction is $100,000.

Silencers can reduce artillery noise by as much as 20 decibels, which may not seem like much, but is the difference between listening to your television and listening to your blender.
